Both side of my refrigerator are number 9 (coldest), I could not input to decrease (go down) to number 3 (warm). maybe electronic board is problem. And fresh food section is freeze (make ice) so I think defrost themos (censor) is not work.
For the issue with the refrigerator section getting too cold you will want to take the duct assembly out of the unit and check the air damper that is in the duct assembly. Check to make sure that the door on the damper is not broken. If broken then you will need to replace part number WR49X10091. With not being able to input temp change then the issue with the display would most likely be a control board issue WR55X10172.
The ice maker works but it will not dispense water or ice. On the panel only the water lights up.
You will want to check the wire harness connection at the bottom of the door to ensure that there is not a broken or loose wire. If this checks ok then the most likely cause of failure would be the dispenser control board.
the water and ice dispenser on my GE refrigerator won't work. When the switch is depressed the light dims or blinks, nothing else happens. the refrigerator/freezer works well otherwise.
Answer Wally, You're on target. The dim, blinking lights and no operation of the dispenser indicates a weak circuit on the main control board(mother board) WR55X10942 on the back of the refrigerator. If you press and hold the paddle long enough, chances are the compressor will also shut down. This is due to an issue in the control board circuitry.
